24 Claims.

My invention relates to coating compositions and more particularly tothe method of making wrinkle drying varnishes which can be used toproduce difierent textural wrinkle patterns. The invention is applicablefor producing clear varnish wrinkle finishes without employing blownoils as a constituent, thereb'y materially reducing the cost andimproving the product.

?Wrinkle finishes as heretofore made in the art have been compoundedfrom so called fwrinkling oils which oils comprise raw China wood oil,blown drying oils, such as China wood, linseed, perilla, oiticica, etc.Other paint and varnish oils of the so called non-wrinkling type, suchas soya bean, chia, walnut, hempseed, lumbang, poppy seed. sunflowerseed, safilower seed, castor, fish, etc., may be utilized. Large amountsof the non-wrinkling oils, however, cannot be used in the formulation ofWrinkle finishes;

otherwise the wrinkling of the finish on drying is inhibited. Prior tomy invention, it has been necessary to use blown or preoxidized oils incompounding wrinkle finishes in order to obtain the most satisfactoryresults. This was particularly true where clear wrinkle varnishes ofsprayable consistency were desired.

The disadvantage of using blown oils lies in their instability. Thisinstability results from the preoxidation of the oil which oxidationcontinues in a progressive manner after termination of the blowingtreatment. At the beginning of the treatment the oil is soluble in theconventional petroleum or coal tar solvents but as oxidation progressesthe oil becomes increasingly less soluble until finally it precipitatesout in a rubber-like mass. This renders the wrinkle composition unfitfor use. Wrinkle finish coating compositions comprising blown oilconstituents, therefore, cannot be stored for any length of time beforeuse.

It has also been found that in using wrinkle coating com-positions madewith blown oils, a wrinkle finish having very fine texture can not beproduced, the tendency being for the finish to form a coarse or heavytextural wrinkle pattern on drying.

It is an object of this invention to make a wrinkle finish compositionwhich is stable on storing and can be readily modified so as to producecoarse, medium or fine textural wrinkle pattern.

Another object of this invention is to eliminate the necessity of usingblown oils in making wrinkle finishes.

Another object of this invention is to provide a. wrinkle finishcomposition which is comparable to wrinkle finish compositions madeusing blown oils.

Another object is to provide a wrinkle finish varnish base which can beblended with higher or lower viscosity varnishes so as to produce alight or heavy textural wrinkle finish on drying.

Another object is to compound a wrinkle coating composition comprising araw wrinkling oil adapted to be blended with low viscosity varnish toproduce a wrinkle finish having a pattern scarcely discernible to thenaked eye but feeling rough to the touch.

Another object is to provide a wrinkle finish coating. composition whichis useful as a blending agent to produce wrinkle finishes having finertextural patterns than produced by the use of low viscosity wrinklingvarnishes.

Another object is to compound a composition which will dry to a wrinklefinish whereby the desired pattern or texture of wrinkle finish can bevaried by the addition of drying oil fatty acids. Still another objectis to produce a wrinkle drying varnish of sprayable consistency withoutthe use of blown oils.

Typical examples of Wrinkle finish compositions comprising blown dryingoils are;

Example 1 Resin (Congo, kauri, rosin, cumar or Ambero lbs Lead linoleateor acetate"; do 2-3 Cobalt acetate or linoleate do Blown tung oil gals8-10 Petroleum naphtha do 9-12 Toluol or xylol do 10-14 Example 2 Resin(Congo, kauri, rosin, "cumar or Amberol") lbs 100 Litharge do 3 5Manganese linoleate or borate do 2-3 Blown linseed oil gals 15-25Petroleum naphtha do 8-12 Toluol or xylol do 15-20 In order to eliminatethe use of blown oils as illustrated in the typical examples of wrinklefinishes given, the formula for producing a wrinkling varnish base of myinvention is as follows:

In the foregoing varnish formula it will be understood that variousresins may be utilized in place of those mentioned. Resins which aresuitable are kauri, dammar, Congo, "cumar, pontianak, Manila, Zanzibar,elemi, mastic, copal, sandarac and the like. Further other phenolformaldehyde resins of the rosin. fossil resin and ester gum modifiedtype which are readily compatible with the oil vehicle may be used. Alsoglycerol phthalic resins of the oil soluble type may be utilized, ormixtures of the above resins.

Similarly other wrinkle oils such, as raw oiticica, poyok and equivalentoils may be substituted for raw China wood oil. The bodied linseed oilemployed is the grade known in the trade as "varnish linseed." Thisproduct comprises linseed oil which has been processed by heat treatingthe same between 575 to 600 degrees F. until a desired degree ofviscosity-is obtained.

The preferred method of making varnish A is to heat all of the Chinawood oil and approximately to A of the resin together in a vessel to atemperature around 540 degrees F. Thereafter the metallic drier, linseedoil and the remainder of the resin are added. When the resin isdissolved the varnish base can be cooled and thinned with the solvent orit can be heated longer to obtain a higher viscosity before thinning.

I have discovered, however, that if the varnish base is cooled quicklyafter the second portion of resin is dissolved a clear wrinkle varnishcan be made having improved spraying and wrinkling properties. Theessential step in making varnish A is the sudden chilling or cooling ofthe heat treated homogeneous mass at the end of the heat treatment. Thismay be done in any suitable manner such as by the application of coldwater or by refrigeration. By this method of making the wrinkle finishcomposition a sprayable wrinkle finish product is obtained comparablewith that made with blown oils. The wrinkle finish product is alsostable and can be stored. The heat treatment of the varnish may bevaried between a temperature range of 450 to 550 degrees F. butpreferably the heating is conducted above 500 degrees F. a

By maintaining the percentage amount of the total solids in thecomposition the same and heating the product for different lengths oftime, I can regulate the viscosity of the varnish. The longer thevarnish is heated the higher becomes its viscosity and correspondinglythe shorter the period the lower the viscosity. This is true even thoughthe amount of solvent or thinner added may be the same in both cases.

In making a clear wrinkle varnish there is added to the above varnish "Aabout 2 to 5 per cent of a liquid drier. A drier composition which hasbeen found to be very satisfactor for this purpose is as follows:

Liquid Drier ".4.

Cobalt linoleate solid lbs 12-16 China wood oil fatty acids do 8-10Toluol, xylol, petroleum naphtha or coal tar solvent gals 6-8 Otherexamples of liquid driers which may be For producing a wrinkle finishcomposition of the desired textural wrinkle pattern, varnish A may bemade having relatively low or high viscosity as determined by theGardner-Holdt standards for varnish. In general the higher the viscosityof the varnish A the coarser the texture of the wrinkle finish.

Where a finer textural pattern of a wrink-le finish is desired than canbe obtained by the use of a low viscosity varnish. a varnish-likesolution of drying oil fatty acids may be incorporated in varnish A."The following examples are typical:

Varnish "B China wood oil fatty acids lbs 8-10 Toluol or xylol gal 1Varnish "C Linseed oil fatty acids lbs 2-5 China wood oil fatty acids-do 3-8 Toluol or xyl gal 1 By adding various proportions of varnish Bor varnish "C" to a low viscosity wrinkle varnish base made according tovarnish "A," the texture or pattern of the wrinkle produced on drying ismodified. The higher the proportion of varnish' B or C added to varnishA, the finer the texture of the wrinkle finish produced.

In producing the improved wrinkle finish of this invention, articlescoated with the coating composition may be made to wrinkle by baking thecoating at relatively low or high temperatures. For metallic and similarsurfaces a temperature of to 475 degrees F. may be employed. Forapplication of the coating on wood, paper and similar materials asomewhat lower temperature on the order of 125 to degrees F. may beused. Ordinarily baking the finish at elevated temperatures accentuatesthe wrinkling and provides a harder finish. Where a highly elastic filmis desired, the addition of small amounts of non-drying or semi-dryingoils, such as castor oil, raw soya bean oil or similar materials may bemade. Plasticizers such as dibutyl-phthalate or tricresyl phosphate alsomay be utilized.

It will be understood that I desire-to comprehend within my inventionsuch modifications as come within the scope of the claims and thevention.
